Suitability of GGBFS as a cement replacement for concrete in hot arid climates

Robins, P. J. / Austin, S. A. / Issaad, A.

Abstract Three ground granulated blast-furnace slag (GGBFS) concretes (30, 50 and 70% cement replacement) together with an OPC control, all designed for equal workability and 28-day water-cured strength, are compared when subjected to a variety of curing methods and exposure in both a temperate and a hot arid climate. The effect of replacement level on cube and core strengths, ultrasonic pulse velocity, surface hardness, water absorption and permeability are reported. The test showed conclusively that the 50%, replacement level was best and that a GGBFS concrete can be superior to an equivalent all-OPC concrete in a hot climate, provided that proper curing is provided.
